Life’s good these days for Paul Allen. His Portland Trail Blazers are enjoying an incredible NBA record, as are his Seattle Seahawks in the NFL. Microsoft is continuing to flourish, and his investment firm — Vulcan Capital — now has a Palo Alto branch.

Perhaps the last development explains his need to purchase this luxury home in Atherton, Calif. Of course, it doesn’t explain why he needs a house that sprawls over 22,000 square feet, or a 5 car garage.

Allen has never married and has no children. Plus, according to Trulia, he already has “a state-of-the-art residence on tony Mercer Island, with a yacht parked out front. He also owns multi-million-dollar properties all over the world, including estates in France, Hawaii, Malibu, Manhattan, Idaho, Beverly Hills and London. Aside from his residences, Allen has a world-class collection of World War II aircraft, a fleet of private jets and two yachts.” One is a 303-foot-long, $125 million yacht named Tatoosh, and another is is a 414-foot long superyacht named Octopus, which costs “an estimated $400,000 a week to operate.”

The yacht “Octopus” of Microsoft co-founder Paul Allen at anchor at Ushuaia Bay, southern Argentina, on January 31, 2011. A helicopter on board the Octopus (L) was forced to carry out an emergency landing on the bay on Monday but no injuries were reported among its passengers, Navy officials said.

Lest we worry Allen is about to over-extend himself with his Silicon Valley real estate purchase, we should note that Forbes estimates his wealth at $15.8B, making him one of the wealthiest men in the world. In other words, he can afford it.

The home

Clocking in at 22,005 square feet, the main home on Allen’s new property includes all the luxury touches we expect these days:

private setting on a 1.97 acre lot

6 bedrooms

6 bathrooms

spa

theater

7 fireplaces

The guest home, equally lovely but on a smaller scale, adds:

2 bedrooms,

2 bathrooms

full kitchen

The garage offers:

room for 5 cars

a “House Manager Suite”

The home’s linear angles and heavy use of glass seem appropriate for a tech-mogul turned investor billionaire. Allen once again showed his golden touch in all things financial, scoring the property for $27 million – a substantial discount from the original list of $31.8 million.
